The Prohibition era in America, which lasted for well over a decade and—inconceivable as it might be today—effectively banned the sale and production of booze in the United States, ended with the ratification of the 21st Amendment on Dec. 5, 1933.

Prior to the invention of photography in the mid-19th century, the silhouette was considered an effective and inexpensive way to record a person’s likeness or capture a scene. Although the practice can be traced back to the early 17th century, the term ‘silhouette’ derives from the harsh policies of the French finance minister Étienne de Silhouette.

The silhouette reduces an object to its most basic form. Its historical uses in art can be seen in the paper cuts of Hans Christian Andersen and the artwork of Kara Walker. In photographic terms, the silhouette is created in situations where the subject is back-lit. It can be used to hide a person’s identity or highlight their distinctive features, and its graphic form is often used artistically to photograph sport and dance. It heightens drama, adds atmosphere and turns banal scenes into graphic wonders.

More than 200 years ago, the silhouette was the foremost way to document one’s appearance, but it’s still widely used in photographic frames today.
